0:00 Introduction
0:19 The ratio of the length of a rod and its shadow is 1: V3, then find the angle of elevation of the sun's elevation. Hence find the height of the rod, if its shadow is 1253m long at the same time.
1:58 The distance between two vertical pillars is com, and the height of one is double of the other. The angles of elevation of their tops at the mid-point of the line joining their feet are complementary. Find their heights.
5:12 From the top of a 7m high building, the angle of elevation of the top of a cable tower is tº and the angle of depression of its foot is 45 degrees. Determine the height of the tower
7:46 A straight highway leads to the foot of a tower. A man standing at the top of the tower observes a car at an angle of depression of 30 degrees, which is approaching the foot of the tower with a uniform speed. Six seconds later, the angle of depression of the car is found to be 60. Find the time taken by the car to reach the foot of the tower from this point
11:15 high building finds the angle of elevation of the same bird to be 45. Both the bird from the girl.
